WBC lightweight champion Devin Haney explains that former pound-for-pound king Floyd Mayweather, 43-years-old, is training like he's going to face a top welterweight.
Mayweather, a five division world champion, is getting ready for an exhibition fight with Youtube star Logan Paul.
The 25-year-old Paul, who stands at 6'2 and weighs 200-pounds, has a big size advantage against the 5'8 Mayweather, who walks around at 150-pounds.
But Mayweather's tremendous edge in experience and overall skill will be way too much for Paul to overcome.
Mayweather retired from the sport of boxing in August of 2017, with a perfect record of 50-0, when he stopped UFC superstar Conor McGregor in the ten rounds at the T-Mobile Arena in Las Vegas.
He came back in December 2018, when he traveled to Japan for an exhibition fight and demolished kickboxer Tenshin Nasukawa in one round.
Paul made his pro debut in 2019, when he lost a controversial six round split decision to Youbtube rival KSI.
While many expect the fight with Paul to be a mismatch, Mayweather is not taking the contest lightly, according to Haney.
"His work ethic is crazy because he is still working. He still gets up at 5 or 6am to go running," Haney told Sky Sports.
"He is training in the gym. He works like he's going to fight one of the top welterweights today."
Haney, regarded as one of the top lightweights in the world, has learned a lot from spending time with Mayweather in the gym.
"It's great," said Haney. "I'm thankful to spend time and to learn from the Michael Jordan of boxing. He is a guy who has accomplished the most in his era, and someone I can learn so much from."
"He is different when you get to know him, and when you spend time with him. I wouldn't say more humble because I don't feel like he is cocky - he just does what he has got to do to promote himself. He is down to earth."
